"A month from now there will be a huge event in Las Vegas, but two days from now there is the best fight card of the summer, the best fight of the summer, and a great show from top to bottom at Barclays Center in Brooklyn.

"This is a great summer of boxing for SHOWTIME and it's great to be in this room and see all the great attention that this fight card is getting. This is one of the best representations that we can have of our sport. This is one of the most stacked cards I've ever been involved with.

"There are a lot of good reasons to get a ticket and come to Barclays Center on Saturday night. There will be a strong Irish presence on the card Saturday with both Katie Taylor and Noel Murphy entering the ring."
